C is the answer hope that helps have a good day
Answer:
b. 1
Step-by-step explanation:
All first coordinates are 1/2.
Answer: b. 1
8.8 because you need to multiply 1.68 by 10 which is 16.8-8=8.8
Sure! So this is ready as "the cube root of 125". This basically means, "what number cubed can get me 125?"
Let's go through our options.
We can rule out D, as D cubed would be unreasonably big.
We can also rule out C, because 375 cubed is easily over 10000, you know this even if you haven't computed it all, just compute the 300 cubed.
We can rule out B, too. 41 squared is already over 125, therefore it can't be the answer.
Therefore our answer is A, 5. We can check that by cubing 5, and that indeed gets us 125.
Hope this helps!
49x^2 = 36
take square roots of both sides:-
7x = +/- 6
x = 6/7, -6/7.
